2 TO 26 GHz IMAGE REJECTION MIXERS/IF AMP INPUT
MODELS: IRA0226LC1A, IRA0226LC1B AND IRA0226LC1C
FEATURES
• RF/LO coverage ................ 2 to 26 GHz
• IF operation ....................... 20 to 200 MHz
• LO power range ................ +10 to +13 dBm
• Conversion gain ............... 23 dB typical
• Image rejection ................. 20 dB typical
Image rejection mixers are useful for wideband test equipment or ultra-broadband receivers requiring rejection of
an unwanted sideband of signal or noise following a low-noise front-end amplifier. The IRA Series of image rejec-
tion mixers has an integrated IF amplifier, thus making the overall sensitivity less dependent on the load noise. The
mixer/IF interface is also optimized for best 2RF-2LO spur performance.
